How did I put hands on the clock in chapter 5?

Ok not dure how I did it but I dropped through the opening in the ceiling of the right clock tower in chap 5 (the hole between the mirror and the blue chest) - and landed on the clock's hands, enabling me to simply double jump to the chest and caviar next to the boss chamber. Normally there's nothing there...so....Anyone know how I made those hands appear?5 years ago
